COMBINED CHIMNEY AND MANTLE HOLDER.

Original application filed January 7, 1909, Serial No. 471,079.

Specification of Letters Patent.

Serial No. 481,338.

To all whom it may concern:

Be it known that I, WVILLIAM S. STAPLEY, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented a new and useful Combined Chimney and Mantle Holder, of which the following is a specification.

This application is a division of my pending application Serial Number 471,079, filed January 7, 1909.

The invention relates to combined chimneys and mantle holders for incandescent gas burners of the type in which the mantle is, permanently attached to the chimney, the two forming a single article of commerce and both being thrown away when the mantle becomes of no further use, and the invention has for its objects to simplify and cheapen and to generally improve the construction and mode of operation so as to reduce the cost of the entire structure to practically the cost of the mantle and an ordinary holder.

With this and other objects in view I have devised the simple and novel combined chimney and mantle holder of which the following description in connection with the accompanying drawing is a specification, reference characters being used to indicate the several parts:

Figure 1 is a view partly in elevation and partly in section, illustrating the construction and mode of operation of my novel invention; Fig. 2 a plan view corresponding therewith; and Fig. 3 is a section on the line 33 in Fig. 1, looking in the direction of the arrows.

10 denotes a bunsen tube, 11 a chimney tube and 17 a mantle. In order to secure perfect stability and freedom from movement of the chimney and mantle and thereby reduce vibration of the mantle to the minimum, I provide the bunsen tube with a shoulder 16 formed by closing in the metal of the tube upon which the lower end of the mantle tube rests, the mantle tube engaging the bunsen tube closely and keeping the mantle tube and parts carried thereby relatively firm and steady in use.

The mantle is carried by a transparent chimney which is itself carried by chimney tube 11. The chimney comprises a base 27 of light sheet metal which is rigidly secured to the chimney tube, a transparent body ordinarily of mica, indicated by 28, and an angle ring at the top which is indicated by 29 and is also blanked out from light sheet metal. The chimney tube slides over the top of the bunsen tube, the lower end of the chimney tube engaging upper shoulder 16 on the bunsen tube, thereby insuring stability of the chimney and mantle relative to the bunsen tube. The mantle is suspended from a carrier 30 which is made of wire and is provided with a central depression 31 to receive and retain the mantle loop, indicated by 32.

The carrier is attached to the angle ring in a novel way which is an important feature of the invention. The carrier is curved and re-curved and its ends 33 extend downward through holes 34 in the upper side of the angle ring.

35 denotes lugs formed integral with the angle ring from the metal that would otherwise be removed from the center thereof. These lugs are in pairs and are clamped about the carrier, as clearly shown in Figs. 1 and 2, thereby locking the carrier to the angle ring and making it perfectly rigid with the chimney.

Having thus described my invention, I claim:

1. A combined chimney and mantle holder of the character described, comprising a transparent body, an angle ring at the top having holes in the upper side thereof and lugs and a mantle carrier having a central depression to receive a mantle loop and its ends passed downward through the holes in the angle ring and the lugs clamped about the carrier.

ring being clamped about the carrier, for 10 the purpose set forth.

In testimony whereof I afiix my signature, m presence of two Witnesses.
